Abstract
Working within the framework of Coulomb modified Glauber theory, we calculate α particle total reaction cross sections for

Sn at medium energies in the rigid projectile model using the parameters of the phenomenological N–α amplitude. A comparison with the available experimental data shows that, in general, the results of the present calculation are in much better agreement with the data compared to those of the optical limit calculation using the free NN total cross sections.
